| 摘 要： | 以金叶接骨木(Sambucus canadensis‘Aurea’)、紫叶水蜡(Ligustrum obtusifolium Sieb.atropurpurea)、金叶水蜡(Ligustrum obtusifolium Sieb 'Aurea)一年生离体枝条为试验材料,研究低温胁迫(0、-6、-12、-18、-24、-30、-36℃)与室温条件下(CK)的脯氨酸(Pro)、丙二醛(MDA)含量及相对电导率等生理指标的变化规律.结果表明,随着处理温度的降低,离体枝条脯氨酸、丙二醛含量呈上升趋势,细胞相对电导率也不同程度地增加;对各项指标测定结果进行分析表明,3种彩叶灌木离体枝条耐低温的能力为金叶接骨木＞紫叶水蜡＞金叶水蜡,后二者差别不明显.

| Abstract: | Using 1-year-old in vitro branches of Sambucus canadensis ‘Aurea’,Ligustrum obtusifolium Sieb ‘Aurea’,L.obtusifolium Sieb.atropurpurea as experimental material,the variation of proline(Pro),malondialdehyde(MDA) and relative conductivity and other physiological indicators at low temperature stress(0 ℃,-6 ℃,-12 ℃,-18 ℃,-24 ℃,-30 ℃,-36 ℃) and room temperature(CK) were studied.The results showed that the content of Pro and MDA and relative electric conductivity in branches presented an upward trend with the decrease of temperature.The cold-resistance of three in vitro color-leafed branches ordered S.canadensis ‘Aurea’,L.obtusifolium Sieb.atropurpurea,L.obtusifolium Sieb ‘Aurea’;and there was no significant difference between the latter two. |
